Holding a 3 port valve

Might be wrong

I am trade, normally drain down but if there's an easier way.

 

[Riley]

Freezing or bung. That's really it

You could always just freeze one pipe with a cheap freeze tin kit and also have system bunged to deal with the other two pipes. Would save you spending on more freeze tins.
If you bung the system you might find you will be able to change the valve with little water problem as your 3 pipes are all at identical level.

Bung it first and after taking the pressure totally off the system from a drain point, then see if cracking all the 3 nuts open allows any water problems. Have a freeze kit with you if you need it. Water is a strange thing and I never can be sure. Some jobs I expect to be troubled with water and find none

Bunging is so easy, for added comfort close the pump valves and return valve if there is one.

As Leo21 says, I've done it lots of times without any problems, just get everything ready and to hand B4 you start
